Question
The gain of an antenna is 32 dBi, what is the gain of this antenna in dBd?
- 29.86 dBd
- 32 dBd
- 32.14 dBd
- 34.14 dBd
Solution
The gain of an antenna in dBd can be calculated from its gain in dBi by subtracting 2.14. This is because dBi is a measure relative to an isotropic antenna (an ideal antenna that distributes power equally in all directions), while dBd is a measure relative to a dipole antenna. A dipole antenna has a gain of 2.14 dBi.
So, if the gain of the antenna is 32 dBi, its gain in dBd would be:
32 dBi - 2.14 = 29.86 dBd
So, the correct answer is 29.86 dBd.
